View Full Version : About Laser Scanning - Triangulation and PointClouds

09-14-2014, 06:09 AM
Hello everybody, i working in a project of 360 laser 3d scanning in a turntable (Camera and Laser dont move and the distance to turntable is always the same), but have some questions which i don't find answers for them, then i expect find here.

1 How is the process for detect the position of each point in a captured image ? Like the example below, but with monochrome, how the process will know which the white stripe/contours is a place who you need place the points ?


2 How is attached each point in a tridimensional space ? Example: p(0,2,7); p(2,6,3);...;.

Thank for Help. Sorry for anything.

OpenGL(R) is not an image processing library (it does not do image processing and also is not a library).

If you don't want to reinvent an algorithm yourself (homography or whatever suitable, I don't know a lot on computer vision tough), you might want to look at the unrelated OpenCV (http://opencv.org/) project.
